The utility model has the beneficial effects that: rotating by motor driven turntable, then connecting rod mechanism movement is driven, thus Linear motion is converted by rotary motion, then the clamping jaw by being fixed in link mechanism one end can press from both sides disc-like workpiece It fastens or unclamps, present apparatus structure is simple, suitable for the disc-like workpiece of various sizes, when can effectively shorten product thread-changing Between, improve production capacity.

Detailed description of the invention

Utility model is described further below in conjunction with accompanying drawings and embodiments, in attached drawing:

Fig. 1 is the structural schematic diagram of the rotating clamp of the utility model embodiment；

Fig. 2 is another structural schematic diagram of the rotating clamp of the utility model embodiment；

Fig. 3 is the cross-sectional view of the rotating clamp of the utility model embodiment.

Specific embodiment

Now in conjunction with attached drawing, elaborate to the preferred embodiment of the utility model.

As shown in Figure 1, 2, the rotating clamp of the present embodiment, including swivel base 1, setting are below swivel base 1 Clamping jaw 2, be uniformly arranged on swivel base 1 for drive 2 clamp or release of clamping jaw multiple link mechanisms 3, setting exist The turntable 4 of drives link mechanism 3 movement of the top of swivel base 1, be arranged in 4 side of turntable for driving the rotation of turntable 4 Motor 5.It drives turntable 4 to rotate by motor 5, then link mechanism 3 is driven to move, to convert straight line fortune for rotary motion It moves, then the clamping jaw 2 by being fixed in 3 one end of link mechanism can be clamped disc-like workpiece 10 fixed or unclamp.This dress It sets that structure is simple, suitable for the disc-like workpiece 10 of various sizes, can effectively shorten product conversion time, improve production capacity.

As shown in Figure 1, 2, 3, the link mechanism 3 includes pull rod 31, the rotation connection that one end is rotatably connected on turntable 4 In the clamping jaw fixing piece 32 of 31 other end of pull rod and setting for guiding 32 motion profile of clamping jaw fixing piece on swivel base 1 Guide groove 11, the clamping jaw 2 and clamping jaw fixing piece 32 are affixed.By the way that pull rod 31 is rotatably connected on turntable, then by leading The motion profile for being rotatably connected on the clamping jaw fixing piece 32 of 31 one end of pull rod is limited to slot 11, the rotation of turntable 4 can be turned The straight reciprocating motion of clamping jaw fixing piece 32 is turned to, clamping and release to workpiece can be completed.

As shown in Figure 1, the rotating clamp further includes at least one photoelectric sensor being arranged on swivel base 1 6 and the sensing chip 7 that is arranged on turntable 4.When rotating clamp is clamped work, turntable 4 can drive sensing chip 7 one Play rotation, when sensing chip 7 is turned to the 6 corresponding position of photoelectric sensor being arranged on swivel base 1, optoelectronic induction Device 6, which can transmit signal, powers off motor.Therefore the position that photoelectric sensor 6 can be adjusted according to the size of workpiece, can be completed Clamp disc-like workpiece 10 while motor 5 stop operating, can effectively prevent because 5 amount of spin of motor it is excessive caused by disc-like Workpiece 10 damages.

As shown in Figure 1, 2, link mechanism 3 there are four being uniformly arranged on the swivel base 1, by swivel base 1 Four link mechanisms 3 are uniformly arranged, disc-like workpiece 10 can be supported with multiple spot, clamping effect is better.The rotation It is the One On The Chassis to set there are four photoelectric sensor 6, according to the change of workpiece size, electric inductor 6 can be placed into four it is different Position can meet the needs of four kinds of workpiece sizes.In use, the photoelectric sensor 6 of corresponding workpiece size need to only be opened, remaining Three photoelectric sensors 6 are closed, and can be used, convenient and efficient, and versatility is high.

As shown in Figure 1, the rotating clamp further includes the shaft 8 being rotatably arranged on swivel base 1, is installed in electricity Active synchronization belt wheel 91 on machine, the driven synchronous pulley 92 and synchronous belt 93 being arranged in shaft 8, the turntable 4 are fixed In shaft 8.By the cooperation between active synchronization belt wheel 91, shaft 8, driven synchronous pulley 92 and synchronous belt 93, To complete the transmitting that motor 5 arrives 4 torque of turntable.

As shown in Figure 1, the guide groove 11 be equipped with guide sleeve or guide rail, by guide groove 33 increase guide sleeve or Guide rail can effectively prevent when clamping jaw fixing piece 32 does first motion and rotate or deviate, and improve clamping precision and accurate Property.

As shown in Figure 1, with the contact surface of disc-like workpiece 10 being curved surface on the clamping jaw 2, by by clamping jaw 2 and disc-like The contact surface of workpiece 10 is set as curved surface, can effectively prevent when the movement of clamping jaw 2 shifts and causes to disc-like workpiece 10 Damage, save production cost.Support protrusion 21 is provided with below the clamping jaw 2.It, can be effective by increasing support protrusion 21 Support workpiece, when clamping, need to only be bonded fixed with regard to achievable clamping.Disc-like workpiece 10 is clamped without using frictional force, it can Prevent clamping power excessive to damage caused by disc-like workpiece 10.

As shown in Figure 1, multiple lightening holes 12 are uniformly provided on the swivel base 1, before not influencing structural behaviour It puts, opens up multiple lightening holes 12, production cost can be effectively reduced.

It should be understood that above embodiments are only to illustrate the technical solution of the utility model, it is rather than its limitations, right For those skilled in the art, it can modify to technical solution illustrated in the above embodiments, or to part of skill Art feature is equivalently replaced；And all such modifications and replacement, it all should belong to the protection of the appended claims for the utility model Range.
